## Embedding Media in HTML
Multimedia elements like videos, audio, and external content enhance user engagement and interactivity on a webpage. In this lesson, we’ll cover how to add videos, embed audio, and use `<iframe>` for embedding content like YouTube videos or maps.

### **Adding Videos with the `<video>` Tag**
The `<video>` tag allows you to embed video files directly into your webpage.
#### **Basic Structure of the `<video>` Tag**
```html
<video src="video.mp4" controls></video>
```
- **`src`:** Specifies the path to the video file.
- **`controls`:** Adds playback controls like play, pause, and volume.
- **`autoplay`:** Automatically plays the video when the page loads.
- **`loop`:** Makes the video replay continuously.
- **`muted`:** Starts the video with the sound muted.
- **`poster`:** Specifies an image to display before the video starts playing.
---
#### **Example: Adding a Video**
```html
<video src="sample-video.mp4" controls width="600"></video>
```
**Result:** A video player with controls for playback.
---
#### **Adding Multiple Video Sources**
You can provide multiple video formats for compatibility with different browsers using `<source>` tags.
```html
<video controls width="600">
<source src="video.mp4" type="video/mp4">
<source src="video.webm" type="video/webm">
Your browser does not support the video tag.
</video>
```
**What happens?**
- The browser picks the first supported format.
- The fallback text appears if the browser doesn’t support videos.
---
#### **Advanced Example:**
```html
<video controls autoplay muted loop width="600" poster="poster-image.jpg">
<source src="video.mp4" type="video/mp4">
<source src="video.ogg" type="video/ogg">
Your browser does not support the video tag.
</video>
```
**Features:**
- The video plays automatically (`autoplay`) in a loop (`loop`).
- The audio is muted (`muted`).
- Displays a poster image before playback.

### **Embedding Audio with the `<audio>` Tag**
The `<audio>` tag lets you add audio files to your webpage.
#### **Basic Structure of the `<audio>` Tag**
```html
<audio src="audio.mp3" controls></audio>
```
- **`controls`:** Adds playback controls like play, pause, and volume.
- **`autoplay`:** Starts playing the audio when the page loads.
- **`loop`:** Repeats the audio continuously.
- **`muted`:** Starts the audio muted.
---
#### **Example: Adding an Audio File**
```html
<audio src="sample-audio.mp3" controls></audio>
```
**Result:** An audio player with controls.
---
#### **Adding Multiple Audio Sources**
Provide multiple formats for broader browser support.
```html
<audio controls>
<source src="audio.mp3" type="audio/mpeg">
<source src="audio.ogg" type="audio/ogg">
Your browser does not support the audio tag.
</audio>
```
**Fallback Text:** "Your browser does not support the audio tag" appears if the browser cannot play audio.
---
#### **Advanced Example:**
```html
<audio controls autoplay loop muted>
<source src="audio.mp3" type="audio/mpeg">
<source src="audio.ogg" type="audio/ogg">
Your browser does not support the audio tag.
</audio>
```
**Features:**
- Audio plays automatically (`autoplay`) in a loop (`loop`).
- The volume starts muted (`muted`).

### **Using `<iframe>` for Embedding Content**
The `<iframe>` tag is used to embed external content, such as YouTube videos, maps, or entire webpages.
#### **Basic Structure of the `<iframe>` Tag**
```html
<iframe src="URL" width="600" height="400"></iframe>
```
- **`src`:** Specifies the URL of the content to embed.
- **`width` and `height`:** Define the size of the embedded frame.
- **`allowfullscreen`:** Enables fullscreen mode for the embedded content.
---
#### **Example: Embedding a YouTube Video**
```html
<iframe
src="https://www.youtube.com/embed/dQw4w9WgXcQ"
width="560"
height="315"
frameborder="0"
allowfullscreen>
</iframe>
```
**Result:** A YouTube video embedded in your webpage.

#### **Embedding Google Maps**
```html
<iframe
src="https://www.google.com/maps/embed?pb=!1m18!1m12!1m3!1d3151.83543450923!2d144.96305731566795!3d-37.81627944201492!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x6ad642af0f11fd81%3A0xb1d6b6b3c07e8d35!2sMelbourne%20Central!5e0!3m2!1sen!2sau!4v1674552397812!5m2!1sen!2sau"
width="600"
height="450"
style="border:0;"
allowfullscreen
loading="lazy">
</iframe>
```
**Result:** A Google Map embedded in your webpage.

### **Best Practices for Embedding Media**
1. **Optimize Media Files:**
- Use compressed formats (e.g., WebM for videos, OGG for audio) to reduce load times.
2. **Use Descriptive Text:**
- Provide clear alt text or fallback content for accessibility.
3. **Ensure Compatibility:**
- Include multiple file formats for broader browser support.
4. **Lazy Loading:**
- Use `loading="lazy"` for iframes to improve performance.

### **Summary**
- Use the `<video>` tag to embed videos with attributes like `controls`, `autoplay`, and `loop`.
- Use the `<audio>` tag for embedding audio with similar attributes.
- Use the `<iframe>` tag for embedding external content like YouTube videos or maps.
